(GSM 11.11 version 6.2.0 Release 1997)61TS 100 977 V6.2.0 (1999-05)10.3.16 EF FPLMN (Forbidden PLMNs)This EF contains the coding for four Forbidden PLMNs (FPLMN). It is read by the ME as part of the SIM initializationprocedure and indicates PLMNs which the MS shall not automatically attempt to access.A PLMN is written to the EF if a network rejects a Location Update with the cause "PLMN not allowed". The ME shallmanage the list as follows.When four FPLMNs are held in the EF, and rejection of a further PLMN is received by the ME from the network, theME shall modify the EF using the UPDATE command. This new PLMN shall be stored in the fourth position, and theexisting list "shifted" causing the previous contents of the first position to be lost.When less than four FPLMNs exist in the EF, storage of an additional FPLMN shall not cause any existing FPLMN tobe lost.Dependent upon procedures used to manage storage and deletion of FPLMNs in the EF, it is possible, when less thanfour FPLMNs exist in the EF, for 'FFFFFF' to occur in any position. The ME shall analyse all the EF for FPLMNs inany position, and not regard 'FFFFFF' as a termination of valid data.Identifier: '6F7B' Structure: transparent MandatoryFile size: 12 bytesUpdate activity: lowAccess Conditions:READUPDATEINVALIDATEREHABILITATECHV1CHV1ADMADMBytes Description M/O Length1 - 3 PLMN 1 M 3 bytes4 - 6 PLMN 2 M 3 bytes7 - 9 PLMN 3 M 3 bytes10 - 12 PLMN 4 M 3 bytes- PLMNContents:Mobile Country Code (MCC) followed by the Mobile Network Code (MNC).Coding:according to GSM 04.08 [15].For instance, using 246 for the MCC and 81 for the MNC and if this is stored in PLMN 3 the contents is asfollows:Bytes 7-9:'42' 'F6' '18'If storage for fewer than 4 PLMNs is required, the unused bytes shall be set to 'FF'.10.3.17 EF LOCI (Location information)This EF contains the following Location Information:- Temporary Mobile Subscriber Identity (TMSI)- Location Area Information (LAI)- TMSI TIME- Location update statusETSI
